Lucas Posted January 22, 2009 Report Share Posted January 22, 2009 Sorry for the bad pun. My little 37L tank has had an ongoing problem with foam forming around the rim of the tank. Can anyone say what would be causing this? It is a planted tank with 2 serpae tetras and 1 small bristle nose. AquaClear 150 with standard foam block and filter floss at the top. 1 Large piece of wood (this could be bad?). Quote Link to comment Share on other sites More sharing options...
supasi Posted January 22, 2009 Report Share Posted January 22, 2009 Excess protiens in water coloumn maybe?? What do you feed them? Quote Link to comment Share on other sites More sharing options...
Stella Posted January 22, 2009 Report Share Posted January 22, 2009 a fairly good indicator of needing a waterchange. As is pretty much everything :roll: When in doubt, do a waterchange. .... and when everything is going well, do a waterchange! :lol: Quote Link to comment Share on other sites More sharing options...
Lucas Posted January 22, 2009 Author Report Share Posted January 22, 2009 Yep, you're probably right :oops: . At the moment, it gets a vaccuum every other week and about 1/4 water change every week. The foam still seems to build up within a couple of days. I'm just surprised at how quickly the water spoils! Perhaps over feeding? The tetras get approx 3-4 tetra-color granules per day and the bristle nose gets half a pleco spirulina disk per day. Quote Link to comment Share on other sites More sharing options...
supasi Posted January 22, 2009 Report Share Posted January 22, 2009 Possibly the wood. I have a large container outside with lots of wood in it and when I put the hose over it to top it up, it bubbles up heaps. If your filter is a hang on the back style it could be doing the same?? Is your water coloured by the leeching tannins from the wood?? HTH Quote Link to comment Share on other sites More sharing options...
Lucas Posted January 22, 2009 Author Report Share Posted January 22, 2009 Yeah, I have a HOB filter. The water does come out a little brown. I might try taking the wood out and keep doing the same water changes for a while. I'll let you know in a couple of weeks. Thanks Quote Link to comment Share on other sites More sharing options...
Stella Posted January 23, 2009 Report Share Posted January 23, 2009 Supasi, I doubt it is the wood. I guess your wood is outside and in the sun? Probably bubbles of gas created by the various biofilms/algae/bacteria etc and the effects of the warm water. Brown water/tannins are not a problem. More an aesthetic thing, some people like it, some don't. I am still sticking with the most likely option: more water changes Quote Link to comment Share on other sites More sharing options...
